ROCK AND ORE CRUSHER.

- Specification of Letters Patent.

Patented July 7, 1908.

Application filed May '7, 1506. Serial No. 315,611.

To all whom it may concern:

Be it known that 1, WILLIAM H. LLOYD, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Rock and Ore Crusher, ofwhich the following is a specification.

This invention relates to means for disintegrating rock and the like,and one of the principal objects is to provide a novel structure, whichwhile entirely effective for the urpose, is very compact, com arativelyight in weight, is made up of easi y detachable sections that arerelatively small, so that the same may be readily packed upon animals,or the like for transportation, and yet when set up is rigid and strongto withstand the necessary rough work and hard usage incident to itsuse.

A further object is to provide a structure of this character, whereinthe driving shaft is to a very great extent relieved of the lateralstrain im arted thereto by the operation of the movab e jaw.

The referred embodiment of the invention is'i lnstrated in theaccompanying drawings, wherein Figure 1 is a side elevation of themachine. Fig. 2 is a top plan view of the same. Fig. 8 is a verticallongitudinal sectional view therethrough. Fig. 4 is a horizontalsectional view. Fig. 5 is a detail cross sectional view on the line 5'5of Fig. 3. Fig. 6 is a detail view partially in section of a sli htlymodified form of construction.

imilar reference numerals designate cor responding parts in all thefigures of the drawings.

In the embodiment illustrated, spaced side walls 6 are employed that areprovided on their outer sides with outwardly extending reinforcing ribsor projections 7 and inwardly extending ribs 7 side walls at one end,and an end wall 9 is located against the opposite ends of the side wallsand projects beyond their outer sides, as shown at 10. This end wall isprovided with an intermediate thickened portion 11, against which theends of the side walls abut, and the projecting portions 10 have lugs 12that engage the outer sides of the side walls. The end and side wallsare detachable, but are rigidly secured together by tie bolts 13. Saidtie bolts ass through the projecting portions 10 of t e end wall andthrough the reinforcing projections or lugs 7 of the side A web 8connects the walls, the bolts having heads or nuts 14 on their ends. Theside walls are also tied together by transverse pins 15 and 16 thatbridge the space between said side walls and extend through thereinforcing ribs or projections 7. The pins are, in turn, held in theside walls and against movement by set screws 17. It will thus beevident that while the frame is composed of a number of comparativelysmall and light parts, which can be readily assembled or disassociated,when said frame is set up, it is very strong and rigid.

A stationary jaw 18 is preferably located on the inner side of the endwall 9 between the side walls and clamped between said stationary jawand the ribs 7 are end plates 9. A swinging aw 19 is loosely journaledon one of the tie pins, as 16. In the present embodiment, this jaw ishung from its upper end, though the arrangement may be varied, as willbe evident to those skilled, in the art. A lever 20 is loosely fulcrumedon the other tie pin 15, this lever having a suitable head 21, in whichis seated a bearing 22. The rear side of the swinging jaw 19 is also provided with a bearing 23, and a link plate 24 connects the head of thelever and the jaw, said link plate having its ends located in thebearings 22 and 23, as clearly shown in Fig. 3. It will be observed thatthe lever is disposed entirely between the side walls and above theirlower edges. Its rear end is bifurcated and embraces the lower end of apitman 25 to which it is connected by a pivot pin 25. The upper end ofthe pitman is engaged with the crank 26 of a driving shaft 27.

It will be observed by reference to Fig. 3 that the lever 20 and link 24are disposed in alinement and that the fulcrum of the lever, theconnection of said lever with the pitman and the bearings of the linksare disposed in substantially horizontal alinement between the sidewalls, all of said devices being wholly located between said walls.

The driving shaft is journaled in cars 28, located on the side walls,and said drivin shaft is referably provided with the usuzil fly whee s29 and driving pulley 30. The driving mechanism is of course for thepurpose of swinging the jaw 19 towards the stationary jaw 18, but inorder to move it in an opposite direction, a coiled spring 31 is empeyed, said spring being located on a draft rod 32, which 1s hinged, asshown at 38 to the swinging jaw, said draft rod passing through the web8. The spring 31 bears at one end against said Web 8, and at its otherend against an abutment 34 secured to the rod.

It is believed that the operation of the structure will be readilyapparent. When the driving shaft 27 is rotated, the pitman 25 is givenan up and down movement, thus causing the swinging of the lever 20. Thelever, operating through the link 24, efiects the swinging of the jaw19, thus crushing the material placed between said jaw and the jaw 18.The size of the product allowed to pass through the machine can bereadily varied by introducing links of different lengths between thelever and swinging aw. Moreover, while in the present embodiment, thelever is fulcrumed between the power and the load, it will be evidentthat the arrangement may be varied to a considerable extent withoutdeparting from thespirit of the in vention. The machine, as thusconstructed, is very compact, so that it will occupy but very littlefloor space, is comparatively light in weight, and the sections thereofmay be easily detached and packed. As already shown, the frame or bodyof the machine is strongly braced, and moreover, the tie pins constitutejournals or fulcrums for the lever and jaw. In this structure, it willbe noted that the power is delivered to the swinging jaw through thelever 20, and as the long arm of the lever is connected to the drivingshaft,

the lateral strain upon said shaft will be com paratively light.

It will of course be understood that the structure shown is open tovarious changes and modifications. Thus while links 24 of differentlengths may be interposed between 1 ing held by suitable means, as forinstance,-

screws threaded into the said enlargement 7, and engaging the oppositeends of the boxings.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is p In acrusher of the character described, the combination with side wallshaving outstanding projections and inset ribs, of an end wall locatedagainst the ends of the side walls and projecting beyond their outerfaces, said end 'wall having a thickenedportion fitted be tween the sidewalls, a stationary jaw located upon the thickened portion, side platesinterposed between the ribs of the side walls and the stationary aw,holding bolts passing through the projecting ends of the end walls andthe outstanding projections of the side walls, tie rods bridging thespace between the side walls, certain of said rods having their .endslocated in and secured to the outstanding projections, a movable jaw,and actuating means therefor'including a device jour- 11a ed on one ofthe tie rods.

In testimony, that I claim the foregoing as my own, I have heretoaffixed my signature in the presence of two witnesses.

WILLIAM H. LLOYD.
